Don't discount electrical, my V8 kept picking up a slight miss/hesitation on medium to hard acceleration and wouldn't rev to limit easily about 20k after changing several sets...100k irridium plugs?? Eventually found some copper slip grease, put that on the tip where the lead connects, perfect! Worth a try.. Sent from my HTC_PN071 using Tapatalk

Ps, differences in motors might be gearing, jetting, cams and so on. You probably need to find a manual(chlymer). Eg, vf750s (shaft drive) motor turns in reverse, has six gears as opposed to 750f, five gears. You're going to have to research! Sent from my HTC_PN071 using Tapatalk

Look into VF1000RS thread on VF400 resto mod, he put a magna 400 motor into a vf400 frame, so it can be done. As Jeremy62 said, may just be electrical(timing points etc). Don't see any response about the colour of the oil? It is normally water that makes it Brown, but time and storage may also do that! Cheap oil change may suffice, but change it once you figure motor is ok. Sent from my HTC_PN071 using Tapatalk

Do you mean splitting the heads? Is there anything in the way other than the bolts? Can I do a compression test turning it by hand, or maybe a drill? Drill may work if all plugs are out! Just jump straight to a battery would be easier. Someone may have a better method, but I'd be rinsing the motor with paraffin before spinning it to much. If your oil looks as it does from the sump, it's not going to look good in the rest of the motor. Sent from my HTC_PN071 using Tapatalk

Don't know about this model, but normally pedal is on a spline, you may have to dismantle and move it one tooth. Or it could be a locking nut behind rearsets linked to master cylinder. Sent from my HTC_PN071 using Tapatalk

Katie, don't sweat it... I think if someone started a thread on what bikes everyone has ridden I think a few skeletons would come out of the closet! One of my bikes was a MB100 delivery without the box at least. It did have a single seat with metal rack though. Sent from my HTC_PN071 using Tapatalk

Gimp! Seriously? Haven't had them side by side, but 1000 frame looked to be shaped differently at the front. Does it slot in or some modification? Interesting, have another bike for another project..... Sent from my HTC_PN071 using Tapatalk
